| This study aimed to evaluate the effect of row spacing and nitrogen topdressing fertilization of two materials (genotype 07SEQCL441 CL and cultivar BRS Esmeralda) on the plant height, yield components, grain yield, and quality of an upland rice crop grown in a no-tillage system. Trials were conducted for two growing seasons under field conditions in a 3 x 4 factorial, randomized, complete block design, with four replications. For each material, treatments consisted of the combination of row spacing (0.225, 0.35, and 0.45 m) with nitrogen (N) applied as topdressing (0, 50, 100, and 150 kg ha-1). The lowest row spacing (0.225 m) for genotypes 07SEQCL441 CL and BRS Esmeralda provided a higher number of tillers, number of panicles m-2, and grain yield of rice.... |

| This study was conducted to measure the effects of the timing of nitrogen fertilization (NF) on soil N-NH4+ and N-NO3-, macronutrient contents in the leaves and grains, and the grain yield of super early genotypes (SEG) of common bean. Field experiments were performed for four growing seasons in an Oxisol soil in Santo Antônio de Goiás, Brazil, using a randomized block experimental design in a split plot scheme. The plots were planted with common bean SEG, and the subplots were the NF timings, including a treatment without N fertilization. The available soil N with improved fertility and medium to high levels of organic matter were enough to meet the N demands of the common bean crop in order to achieve yields of up to 3,000 kg ha-1. Fertilization with N,... |
